HOSE COUPLING.

Application filed February 15, 1921.

To all whom it may canoe m Be it known that 1, Jason M. RUHMANN, acitizen of the United States, residing at San Antonio, in the county ofBexar and State of Texas, have invented a new and useful Hose Coupling,of which the following is a specification.

This invention relates to detachable pipe couplings, and moreparticularly to a pipe coupling designed for coupling a hose or the liketo a spigot.

The primary object of the invention is to provide a device of thischaracter which will grip the spigot associated therewith, and force thesame into the coupling forming a part of the device.

A. further object of the invention is the provision of spring tensioningmeans for insuring a water-tight connection between the coupling andspigot.

With the foregoing and other objects: in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention. 7

Referring to the drawing Figure 1 illustrates a front elevational viewof a coupling constructed in accordance with the present invention.

Figure 2 illustrates a side elevational view of the same.

Figure 3 illustrates a sectional view taken on line 8 3 of Figure 1.

Referring to the drawing in detail, the

" designates a spigot reference character 0 which is of the usualconstruction, the same being provided with a flange 6, and a thread edextension 7. The coupling comprises a circular body portion 8 that isprovided with an upper recessed portion to accommodate the extension 7and a lower extension 9, which is threaded to be positioned in the usualconnecting ring of a hose.

Extending laterally from the body portion 8 on opposite sides thereof,are the pins 10 which accommodate the loop portions 11 of the operatinglever 12, so that the operating lever may have pivotal connection withthe body portion 8.

Serial in). 445,154.

The lever 12 is formed of a length of wire bent intermediate its ends toprovide a handle portion, the ends of the wire being formed into adouble loop, one loop being indicated at 11 while the other loop is indicated by the reference character 12, and as shown, the loops 12 receivethe inwardly 6X tending extremities 13 of the clamping jaw 14.

The jaw 14: also includes a length of wire formed into a pair of arms 15which lie in parallel relation with the mouth of the spigot to which thesame is attached, portions of the wire being formed into the coil 16,the intermediate portion of the length of wire being curved as at 17 toprovide the jaw 14.

From the foregoing it will be seen that when a coupling as described ispositioned over a spigot so that the jaw 14: thereof contacts with theflange 6 of the spigot, movement of the lever 12 to a. position asindicated by Figure 2 of the drawing, draws the arms 15 downwardly andforces the jaw let of the coupling into contact with the spigot, againstthe tensions of the springs 16.

Having thus described the invention, what is claimed as new is In a hosecoupling, a circular body portion having a threaded extension formedintegral therewith, laterally extending pins carried by the bodyportion, an operating lever including a length of wire bent intermediateits end and having loops, a jaw in cluding a length of wire curvedintermediate its ends to embrace a portion of a spigot, the lastmentioned length of metal having coiled portions, portions of the lengthof metal extending through the coiled portion and having theirextremities extending through loops of the lever, and said pinsextending through loops of the lever to se cure the lever to the bodyportion, and said lever adapted to move the spigot engaging section. ofthe lever into close engagement with a spigot when the lever is moved toits active position.

In testimony that I claim the foregoing as my own, I have heretoa'llixed my signature in the presence of two witnesses.

JACOB M. RUHMANN.
